Can't delete PeoplePC folder from Program Files

How can I delete the PeoplePC folder from my Program Files folder?
I deinstalled PeoplePC some time ago using Control Panel, after having
manually deleted some PeoplePC files to resolve conflicting PeoplePC ISP
versions. I had loaded updated PeoplePC ISP, which did not delete or
overwrite the installed version. Conflicts resulted....
Now, there remains a PeoplePC folder (>60mB) in Program Files, which
when I try to delete it, gets to ScamGrd.dll and reads Access Denied.
Make sure disc is not full or write-protected.
Please let me know of a way to remove this folder...
Thanks
Jim
